Standard Construction Drawings

Top

With building regulations changing every 3 years and the efficiency of buildings becoming a higher priority within these changes, achieving the right new-build or retrofit solution at an acceptable cost can be a challenge.

To help the construction industry reduce these costs we have produced a series of standard construction details which help maximise the fabrics contribution in SAP.

Anyone using these details, and crucially all the products specified within the details, will find passing SAP testing much easier, for three key reasons:

  1. Using these drawings reduces the need to use default SAP figures
  2. These drawings make some very simple, but significant, changes to standard build methods which mean the fabric can be used to its maximum capability
  3. The drawings have been independently tested and verified by BRE and …

With this information available to designer and specifier, it should make keeping abreast of the changes considerably easier.

There are no simple right answers any more but these details and the findings from them will provide a simple base line for all domestic construction.

Our approach

Top

The approach we took to create the Standard Construction Details:

  • Standard brick and block construction for the first details with a maximum 100mm cavity
  • Carefully analysed commercial case for all components, delivering the optimum balance of cost versus contribution to SAP
  • Developed the details and sections in 72 cross sections from foundations to just above the eaves
  • With the help of the BRE selected 71 junctions to detail and model to show the biggest gain against the Accredited values in Appendix K within SAP 2009
  • Reduced our thermal bridging for the property and applied these in two test houses
  • Tested and passed all details within SAP, across all building orientations around the compass, from North to South

WARNING

  • The Standard Construction Details can only be submitted with the new Ψ – values if the build is exactly as shown as using the products specified.
  • Any deviation makes the figures void, including using products that have a better U-Value
